I guess I was reading between the lines:
p174 : "There is no such thing as a 'public charter.' 'Public' does not just denote public money but also public accountability; most charter schools are not under the control of the parents and local citizens at all and thus cannot be called public."
p177: "[T]he very competitive landscape that charters are meant to foster creates a structural bias toward dishonest practices."
All public guarantees in this modern time are going to end up with a lot of shitty conditions and outcomes, when people in power don't care about them. Maybe that's a poor reply but it's my reply. The book indeed mixes "just overthrow the culture and machines of capitalism" and "here's some reforms I like, each of which may or may not be precluded by the overthrowy bit, at least a little." I think an unstated and reasonable assumption of FDB's is that if we enact these reforms, it will be because we've convinced the public that public schools and teachers are important. The ideas aren't just to put legal language on paper, they are cultural reforms advanced through appeals to compassion ("As a socialist, my interest lies in expanding the degree to which the community takes responsibility each all of its members, in deepening our societal commitment to ensuring the wellbeing of everyone.") Did the gay and lesbian community get marriage legalized by just crafting the most perfect bill texts?
It's hard to deny that leftism is in a confused way right now. They (generally, not deBoer afaik) think prostitution is liberating!
